In this study, the length-weight relationship (LWR) of 14 fish species including Merlangius merlangus (Linnaeus, 1758),Trachurus trachurus 1758), Mullus barbatus Linnaeus, 1758, Gobius niger Scorpaena porcus Arnoglossus kessleri Schmidt, 1915, Uranoscopus scaber Serranus hepatus Sygnathus thyphle Aphia minuta (Risso, 1810), Trachinus draco Parablennius tentacularis (Brünnich, 1768), Illionymus ...

Three mesh sizes of multiflament trammel nets (22 mm, 24 mm, and 26 mm) were used in Finike bay for red mullet (Mullus barbatus L., 1758). The sampling program was arranged during February to May 2012. Holt (1963) method was used for selectivity of trammel nets. Red mullet was the dominant species in 22 mm mesh size at 52.86%, followed by 25.7% with the 24 mm net and 21.43% with the 26 mm net. ...

Baseline levels of cadmium and lead were determined in muscle tissue and liver of hake (Merluccius merluccius) and red mullet (Mullus barbatus), two commercially important fish species from the eastern Adriatic. Concentrations of trace metals in liver (Cd: 6-183 microg kg(-1) w. wt. ; Pb: 39-970 microg kg(-1) w. wt.) were within the range of recently published data for the Mediterranean. In the...

This study investigated seasonal variations of antioxidant defense enzyme activities: total, manganese, copper zinc containing superoxide dismutase (Tot SOD, Mn SOD, CuZn SOD), catalase (CAT), glutathione peroxidase (GSH-Px), glutathione reductase (GR) and biotransformation phase II enzyme glutathione-S-transferase (GST) activity in the liver and white muscle of red mullet (Mullus barbatus). Th...

The ability to observe and predict trawling-induced patterns at spatial and temporal scales that are relevant to inform realistic management strategies is a challenge which scientists have consistently faced in recent decades. Here, we use fish feeding behaviour, a biological trait easily impaired by trawling disturbance, to depict alterations in fish condition (i.e. individual fitness) and fee...

Stock size and status of red mullet Mullus barbatus were assessed via virtual population analysis yield prediction using on-board observed length-frequency catch data from the north-eastern Mediterranean Sea. The von Bertalanffy growth parameters obtained L∞ = 35.4 cm, k 0.42, t0 0.64, tanc 0.59 Φ′ 2.72. Trawl-type selectivity ogive was calculated as 1.57 years corresponding to 17.1 cm TL. M. i...

Araştırma, 2020 yılı Haziran-Temmuz aylarında Düzce ili Akçakoca ilçesinde balıkçı barınağı ve Su Ürünleri Kooperatifinde gerçekleştirilmiş olup, deniz balıklarının aylık fiyat değişimleri tespit edilerek, türler yıllar arasındaki ilişkilerinin belirlenmesi amaçlanmıştır. Akçakoca’da en çok satışı yapılan hamsi (Engraulis encrasicolus ponticus), istavrit (Trachurus trachurus), mezgit (Merlangus...

In this study 288 length-weight relationships of some fish species from the Turkish coasts Black Sea were gathered 138 studies, which conducted by several researchers between 1989 and 2021. For all species, “b” values ranged 2.49 for Trachurus trachurus to 3.75 Alosa caspia. The expected range 2.5<b<3.5 is confirmed fish. It thought that high b value (3.75) given A. caspia may be ...
